DIPPING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 6'7 0,344, dated March 1 9, 1901.

Application filed October 5, 1900. Serial No. 82,164. (No model.)

To rtZZ whom it may concern:

Be it known that I, J OHANN ADOLPH J ENA, a citizen of the United States, and a resident of South Bend, in the county of St. Joseph and State of Indiana, have invented a new and Improved Dipping-Machine, of which the following is a full, clear, and exact description.

My invention relates to machines for dipping, and particularly forenameling crockery and other goods, and has for its object to provide a machine of comparatively small dimensions, large capacity, and great efficiency.

The invention will be fully described hereinafter and the features of novelty pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is an end elevation of my improved machine, With parts in cross-section. Fig. 2 is a sectional elevation on line 2 2 of Fig. 1; and Figs. 3 and at are detail views showing the holder for the articles to be enameled in longitudinal section and in elevation, respectively.

The machine consists of a suitable receptacle or vat A, adapted to contain the enamel, paint, or other substance with which it is desired to coat the articles. At the top of this vat a shaft B is journaled in bearings B, said shaft being driven by a hand-crank or in any other suitable way, as by a belt 0, adapted to engage a fast pulley B or a loose pulley B The shaft carries a holder for a frame adapted to receive the goods to be treated. Preferably the frame is removable from the holder, so that one operator may fill the frames with articles, while another attends to the machine. The holder, as shown, consists of disks E E, connected at their peripheries by longitudinal bars E and provided adjacent to the said bars inwardly therefrom with apertures E The article, frame, or rack shown in Figs. 1 and 2 consists of a rectangular body F, having arms F projected beyond its inner memher, the free ends of said arms being provided with pins F adapted to enter the apertures E while the inner member of the body is adapted to be seated on one of the bars E The pins F may be slidably mounted in the arms F, or the latter may be made of elastic material, so as to spring the pins F into and out of the apertures E The inner member F and the outer member F are provided with cleats F for holding articles, such as plates or dishes G. To securely hold such articles, the rack has a U-shaped frame H, extending at a right angle to the body F, and the central member H of said frame has sockets or cleats H to receive the edges of the plates G. The free ends of the U-shaped frame are formed with slotted lugs H adapted to detachably receive the ends of a spring lockingplate I. At its center this plate has a screwthreaded aperture, in which is received a clamping-screw J, the end of which is fitted to turn in a smooth-bored socket K, having presser-arms K connected therewith. These presser-arms rest on a presser-bar H which may have cleats H on its inner surface and engages the edges of the dishes G to force them toward the central member H of the frame H. The cleats H and H may be omitted. The construction of the parts I J K K H H H is shown best in Fig. 4, it being understood that these parts are of exactly the same constructionin Figs. 1 and 2, except that the cleats are omitted in Fig. 4.

In Fig. 4 the frame or body F is omitted, and the rack consists exclusively of the frame H, to which in this case the arms F are directly attached.

Figs. 1 and 2 show by full lines the position parts occupy when the rack, with the plates held therein, is secured to the holder. The shaft B is then turned so that the plates will pass under the shaft and through the liquid contained in the vat A. The shaft as a rule is given one revolution for this operation. The holder shown in the drawings may receive four racks; but as a rule only one rack is attached thereto.

To keep the liquid in the vat A homogeneous, I prefer to provide an agitator controlled from the shaft B. The agitator may consist of a bar L, perforated, as shown in Fig. l, and located in the lower portion of the vat. This bar is supported by two arms M on a rockshaft M. The said arms extend through slots A in the bottom of the vat, and to prevent the liquid from escaping through said slots I fit on the upper side of the bottom plates N, curved to conform to the bottom and having apertures through which the arms M pass tightly enough to prevent an undue escape of the liduid, (which is rather thick,) yet loosely enough to let the lever-arms slide through the plates N. The shaft M is rocked by means of a connecting-rod O, secured to an arm M on the shaft and to a crank-pin P on a disk P secured to a shaft P, Which is driven from the shaft B by a belt 0, engaging a pulley P on the shaft 1? and a pully B on the shaft B.

The operation of the machine is very simple, and the dipping of the articles is effected very rapidly and thoroughly, so that a uniform coating is caused to adhere to the surface of the plates or dishes G, Figs. 1 and 2, or of the cups G, Fig. 4, or of any other articles that may be held in the rack.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a dippingunachine, a vat, a holder jonrnaled at the upper portion of the vat and provided with a longitudinal seatingbar at its periphery and a rack secured to the holder and having its inner end member in engagement with the said seating-bar.

2. In a dipping-machine, a vat, a holder journaled at the upper portion of the vat and provided with end portions having apertures, and a rack having a longitudinal inner member adapted to be seated upon the peripheries of said end portions of the holder, and arms extending from the rack inwardly beyond the inner member thereof and provided with projections adapted to fit into the apertures of said end portions.

3. In a dipping-machine, a vat, and a rack supported thereon pivotally, said rack comprising a frame open at one side, a lockingplate at said open side, a presser-bar between said plate and the opposite side of the frame, and an adjusting device connecting the locking-plate and the presser-bar to force the latter away from the open end of the frame.

4. In a dipping-machine, a vat, and a rack supported thereon pivotally, said rack comprising a frame open at one side, a lockingplate detachably secured at said open side, a presser-bar located between said plate and the opposite side of the frame, and a clamping-screw connecting the locking-plate with the pressenbar.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
